HP Media Center replacement

This 420W ATX power supply replaces the original unit in HP Media Center models 7571, 7580, 7590 and 7591. It uses a standard ATX form factor with a single 80mm fan and a switchable 110V or 220V input. The grey enclosure weighs 0.1 and carries the Replace Power RPSU-C99-5 model code.

Connector limits and cable lengths

The unit provides one 15-inch SATA connector, one 14-inch ATX connector supporting 20-pin and 24-pin layouts, one 14-inch 12V ATX connector, two 15-inch large peripheral connectors, two 6-inch large peripheral connectors and one 6-inch small peripheral connector. No additional SATA, PCIe or floppy leads are included beyond the single SATA plug listed.

Check your chassis and wiring first

Verify that your case accepts a standard ATX supply and that the 14-inch and 15-inch cables reach your motherboard and drive positions. Confirm the 20-pin or 24-pin main connector matches your board and that the single 12V ATX lead satisfies the CPU power requirement. Ensure the lone SATA connector covers your storage devices or plan for adapters.

Questions about this item

Which HP Media Center models does this 420W unit fit?

It is listed for the m7571kr, m7580kr, m7580n, m7590kr, m7590n and m7591kr desktops, plus other ATX systems needing a 420W replacement.

What does 420W deliver in a typical desktop build?

The 420W rating supplies enough headroom for a mid-range CPU, integrated graphics, several drives and standard expansion cards without overloading the unit.

How does the 20+4 pin ATX connector work with 20-pin and 24-pin motherboards?

The single 14-inch 20+4 pin cable splits so it plugs into either a 20-pin or 24-pin motherboard socket, covering both legacy and current ATX boards.
